I sometimes struggle with this, so don't take my advice as gospel here and wait for someone else to confirm what I said, or tell me I'm an idiot. But I believe the cathode on the rectifier is always the most positive part of the circuit. So you want the positive side of the cap connected to that.

Also, lytics don't like being hooked up backwards. I would toss them and get new ones, given that you have hooked them up both ways at this point.
